While this weekend marked the unofficial end to summer, there are still weeks left of hot weather in the Carolinas.

But doctors are saying we should already be preparing for fall, at least, when it comes to the flu.

Dr. Justin Moll at Parkside Pediatrics in Greenville said last winter, his office only saw three or four flu cases, as opposed to the few hundred they normally treat. He said the year after a slow flu season - that's this year - is usually challenging.

Moll said this year, the H1N1 strain is still predicted to be a problem, but there are also two brand new strands of flu A and flu B.

Just last week, the Centers for Disease Control reported an Ohio man died from H3N2v, a type of swine flu.

The CDC recommends high risk people to avoid pigs on farms or at fairs this fall and for everyone to wash their hands with soap multiple times a day, stay away from others who are sick and cover their mouths when coughing or sneezing. Experts said the best prevention is the flu shot.

Moll said it is not too early for the shot. He said it may take a week or two for the vaccine to kick in, so getting it earlier in the season is better for prevention.

Clinics are set up across the region. The South Carolina Department of Health and Environmental Control lists them online .

Talk about jumping the shark! Viewer Lisa Malachowski sent us a wild video of a shark feeding on some fish in the ocean off Surfside Beach. The fish keep jumping to get away from it, so it follows suit and jumps high out of the water in pursuit of its meal.
